Buildings Use 40% of U.S. Energy

Americans spend $400 billion annually to power homes and commercial buildings. An estimated $80 billion could be saved through energy efficiency.

NREL's net-zero-energy Research Support Facility employs cutting-edge energy efficiency technologies to consume half the energy of similar buildings. To offset its remaining energy use, the building taps 1.6 megawatts of solar power from its rooftop and nearby parking structures.
